My dog loves these
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
I think this is the 2nd or third I have ordered of this toy. My shepherd mix absolutely loves them. He is a power chewer and these last a few weeks. The shape is great too - he quickly learned how to hold on to it with his paws for maximum chewing efficiency.

Great Supplement for Sticks!
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
This is a great choice for those with furiends that LOVE to chew on sticks. The only con is that once it gets to the curved loop, they have difficulty chewing the loop due to the size of it.

My Corgi Loves These
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
My dog loves to chew on these wooden toys. These are cheap to buy but that is because these wooden toys do not last long, and are not durable for heavy chewers. My dog enjoys gnawing on these for 30 minutes and after a few times, the wooden toy gets worn down with both ends starting to flake. I throw these out every week so he isn’t swallowing a bunch of wooden chips as he chews. However, I keep buying these because I think it’s still better than having him swallowing plastic bits from other plastic toys.
